Description

This sequence change replaces proline with threonine at codon 97 of the VHL protein (p.Pro97Thr). The proline residue is moderately conserved and there is a small physicochemical difference between proline and threonine. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a VHL-related disease. In summary, this variant is a novel missense change that is not predicted to affect protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies.
